TO ALLWHOM IT MAY CONCERN:

Be it known that I, D. SHJ'BIAK'ER, of West Bloomfield, in the connty of Ontario, and State of NewvYork,

have invented certain new and useful Improvements in Coal-Burning Stoves; and I do hereby declare that the following is a full, clear, and exact description-thereof, reference being had to the accompanying'drawings, in which like parts are represented by like letters in the several drawings. i v

The nature of my invention consists in a device, to be hereafter described, for facilitating the clearing of'a fire-cylinder from accumulatingashes, and assisting combustion. i

To, enable others skilled in the art to make and use my invcntion, I will proceed to describe its construction and op ration. i l 4 Q I Figure 1 is a top view of my invention without the fingered ringplac'ed on-the top of the fire-pot, the fingers being on the rotating grate. V

Figure 2 isa top view of my invention without thc fingers -0n the rotating grate, but showing a top ring with its fingers extending downwards, and which can be rotated.

Figure 3 shows a top view of the fire-pot,.without either fingered. ring or rotating grate, showing the lower or stationary part of the grate I v I Figure 4 is a vertical section ot' fig. 1 on line a b. Figure 6 is a vertical'section of fig. 2 on line c d, Figure 6 is atop view of a m-odification of my invention.

Figure 7 is a doublelsection oi fig. 6 on lines fey. V v 4 Figure 8 represents my fingered 'ringas astraight bar, (de'veloped,) to be applied to any fire-box, straight instead of curved. l I

In the drawings, A represents an ordinaryfirc-cylinder for coal.

vI propose to have in all cases a-doublegratc, 7i and 2', onerotating, and the other fixed, both together form- In ti". 1, I show u ri ht fin ers an attached to the u er or rotatin rate h said rate havin holes in its a P a: v a PP g g 2 2 periphery, in which to place a lever in order to facilitate the shaking-process, or turn itlall the way around.

Whilst z' is fixed, his aduplicate; but It can be so rotated as to coincide with 2', save as to one fingerj.

When the finger j is'brought into the position as shown in dotted red'lines 7t, fig. 3, the contents of cylinder can be discharged through the semicircular opening B. r

The duplicate grates referred to, can be made flat or concave, as desired-concave as looking down upon the same. I I

Fig. 2 represents a similar device, no fingers being on the rotating grate it, but I replace the same by using a rin or bar, 0, havin fin ers Z extendin downwards to the rate, and near the fire-c linder onthe inside a a g a g y These fingerson ring 0 replace those' on the upper gratelz, or they may be placed on both, and used in con-' nection.

Now, as to the modification, as shown infigs. 6 and 7. I Here I place the fingers on an outer ring, a, and- I within it. there is placed a rotating grate, 0, one on both n and 0,'to be rotated in the usual way. The inner grate rotates on an axis, e, and it, as well as the outer fingered ring 12, is supported by three or more arms 10,

as seen in figs. 6 and 7. Two arms of this support serve as an'axlc, revolvingin boxes attached to the firepot or cylinder A, whilst the third one can beheld up to the same by any suitable cletcnt, which being released,

lets said inner grate 0 down, dumping ordischarging the contents of fire-pot into any suitable receptacle.

By the use of my fingered rotating grate h, I. greatly facilitate'the shaking down of the ashes in a cylinder or other stovc,-or firc box, particnlarl near its periphery or-outer wall, and the same purpose may be accomplished by rotating my fingered ring C, or both may be used together, if desired. The cfl'ect of this devicejust explained, increases the heating of thc.cylinder or fire-pot, causing greater combustion next to the fire-pot, where the heat is radiated; also keeps the fire-pot from being clogged with cinders or clink'ers." .By the rotation of the upper grate 7L, theopening atB ea-irhe regulated at pleasure, so as topermit any obstructions upon the grate, such asstone or clinker, to he disehar ged withoiit letting down the whole contents of the fire-pot, and

thereby losing the fire.

The rotation of fingered ring C will perform the same oflice or purpose as that which the fingers do on grate h.

Should the fire-box be straight, instead of curved, the fingered rin'g C would be developed, as if it were, straight, as seen in fig. 8, to havea reciprocating er-back-and-forward motion, but performing the same function.

Having thus described my invention, what I elairnasheng and desire to secure by Letters Patent of the United States, is I i 1. A rotating grate, it, having upright fingers -gn, in; combination with the lower grate z, constructed and operated in the mariner substantially as shown and desei'ib'edfand for the purpose set fox'th.

2. The combination of the fingered ring 0, with the fire-box A, fingered rotating grate h, and the under supporting-grate 7:,00'flSt11lCtGd and operated in the manner substantially as shown and described, and for the purpose set forth. I

r 3. The-combinatipnof' a' eylinder or fire-box, or its equivalent, with a fing'ered rihg or bar, G, as show'n and deseribcchand for the purpose setforth.' i i i '4. Theeolnhination ot' rotatinggrate o with a fingered ring, n, constructed andoper'ated inthe manner as shown and described, and for the purpose setforth. i i

5. In combination with said parts. as just described, I elaini the fingered ring C, or its equivalent;
